LIGHT-FIXTURE.

Specification of Letters Patent.

Patented Dec. 5, 1916.

Application filed January 8, 1916. Serial No. 70,999.

To all whom it may concern Be it known that I, JAooB T. JOHNSON, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented a new and useful Light-Fixture, of which the following is a specification.

The present invention appertains to fixtures for gas burners, incandescent electric lamps, or for other lights, and aims to provide a light fixture embodying a shade and holder provided with novel interengageable portions or means, whereby the shade can be readily applied to and detached from the holder, and when applied will be eflectively held or supported by the holder, the shade and holder each being simple, substantial and inexpensive in construction, and being devoid of set screws, .clasps, and similar independent securing elements.

With the foregoing and other objectsin view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure 1 is a perspective view of the shade and holder separated. Fig. 2 illustrates the holder and shade in the act of being assembled or separated, the holder being shown in section and the shade in elevation. Fig. 3 is a bottom plan view of a modified form of holder. Fig. 4 is a view similar to Fig. 1 illustrating a modification.

The holder embodies an annular gallery 1 having a spider 2 for attaching it to the body of the burner or lamp, as usual, the holder being stamped or otherwise formed from sheet metal or other suitable material, and being suitably finished. The lower edge of the gallery 1 is provided with an inturned arcuate flange or lip 3 extending through approximately one-half a circle, or 180 degrees, and having its ends preferably rounded off. Opposite the relatively long flange 3, the lower edge of the gallery 1 is provided with an inturned rounded relatively narrow ear 4, preferably disposed midway between the ends of the flange 3.

The shade E which. may he form and construction, being usually molded of glass, has at its upper end or neck an outturned annular flange 6 of suitable width and thickness in order that the flange is not apt to be broken. This flange 6 is provided at one point only of its periphery with a notch 7 for the passage of the ear 4. At each side of the notch 7, the flange 6 is provided in its under or lower surface with a radial groove 8 engageable with or adapted to receive the ear 4, and the grooves 8 are located a suitable distance from the notch 7 and need not be located far therefrom.

The holder and shade can each be inexpensively manufactured, and are strong and simple in construction.

In applying the shade to the holder, the shade is brought under the holder and tilted slightly, as seen in Fig. 2, and is then moved transversely in the direction of the arrow to move one-half of the flange 6 over the flange or lip 3, in which event the shade can be swung to vertical position to bring the flange 6 completely within the gallery 1, the notch 7 during this operation being in registration with or below the ear 4: in order that said car can pass through said notch when the shade is raised into place. Then, when the flange 6 is above the ear 4, the shade is turned slightly to let the flange 6 seat on the ear 4, and when the shade is turned in either direction, one of the grooves 8 will engage the ear 4 to limit the rotation of the shade, and to hold the shade in place relative to the holder whereby the shade is not apt to be accidentally detached or rotated. The shade is thus effectively held in place, and the interengageable portions of the holder and shade are substantial. The flange or lip 3 provides strong means to assist the ear 4 in supporting the shade, and it will be seen that the flange 6 of the shade need be provided with but a single notch 7, so that the flange 6 is of greatest strength.

The present fixture can be used for gas, electric and other lights, and it is of course apparent that the holder and shade can be manufactured in various styles and sizes.

The holder illustrated in Fig. 3 comprises the annular gallery 1 and supporting spider 2, and the lower edge of the gallery 1 has a air of inturned arciiate flanges or lips 3 w ich have their adjacent ends s )aced apart, and which have their remote en s ter urinating at the ends an are at also de midway between the remote ends of the flanges 3'. The shade is applied to this holder the same as with the first form of holder above described.

- In Fig. 4, the holder comprises the; annular gallery 1 and spider 2", and the gallery 1 is provided with the arcuate flange or lip 8 and the opposite inturned ear l,

as in the form illustrated in Fig. 1, but. in

this case, the flange. 3 and, ear 4: are each corrugated, with the corrugations disposed radially of the gallery. The shade 5 has the outturned annular flange 6 provided .at one point only-with a notch 7 for the passage of the ear 4", and instead of using .the grooves 8, the lower surface of the flange 6 -..is provided with corrugations 8 toengage the corrugations of theflange 3 .and ear 4 when the shade is assembled with the holder. The corrugations 8 may be arranged in series, and may extend completely around the flange 6 with the exception: of

.that point of the? flange having-the notch 7",, or the corrugations :8- may be 1 provided .at certain points. of the flange .6 only, which ever is desired.

- Having thus describedjthe invention, what riscl aimed as new is:

'1. Ashade, holder includingan annular gallery having a relatively long arcuate flange and an opposite relatively narrow ear, and a shade having an annular flange adapted to be shifted transversely onto the first mentioned flange, the shade flange having a single notch for the passage of said ear.

2. Aholder including an annular gallery having an arcuate flange and an opposite ear, and a shade having an annular flange adapted to be shifted transversely onto the first mentioned flange, the shade flange hav- Iinga single notch for the passage of said tioned portion, the shade flange having a single-notch for the passage of the second -1nentioned-portion, said flange being corru- 1 gated, one of said portions being-corrugated forthe engagement of the corrugations of said; flange.

In testimony that I claim the foregoing as;.r ny-, own, Ihavehereto affixed mylsigna- .ture inthe presence of two witnesses.
